Abstract
in English, German

A total of 58 Streptococcus suis strains were isolated from deceased pigs submitted to the National Veterinary Institute, Regional Laboratory in Kuopio, Finland, over a 3 1/2 year period, most frequently from cases of pneumonia. The bacteria were isolated from cases of meningitis, sepsis, rhinitis, endocarditis and abortion. S. suis was also isolated from nasal cavity, lung and brain of some sick piglets without signs of inflammation. Further S. suis was detected in 12 out of 107 tonsils of healthy fatteners tested. S. suis strains were identified by biochemical methods followed by typing. The most common capsular types were 7, 3 and 2, respectively. Only one type 1 strain and no types 6 and 9 strains were found. All S. suis strains tested were sensitive to penicillin and ampicillin.

S. suis is not uncommon in Finnish pig herds. S. suis may be regarded as a potentially pathogenic organism which under certain predisposing conditions may cause serious disease.

Inalles 58 Streptococcus suis stammar isolerades under 3 1/2 år från grisar sända till Statens veterinärmedicinska anstalts regionallaboratorium i Kuopio, Finland. Stammarna påvisades oftast hos grisar med pneumoni. S. suis påvisades också hos grisar med meningit, sepsis, rinit, endokardit och abort. S. suis isolerades också från näshåla, lungor och hjärna hos sjuka grisar utan tecken på infektion. S. suis isolerades också från 12 av 107 tonsiller hos friska gödsvin.

S. suis stammar identifierades med biokemiska tester och typing. De vanligaste kapseltyperna var 7, 3 och 2. Endast en stam av serotyp 1 och ingen stam av serotyp 6 eller 9 kunde påvisas. Alla S. suis stammar som testades, var sensitiva för penicillin och ampicillin.

S. suis är inte ovanlig hos friska grisar. Man kan anse S. suis som en potentiellt patogen organism, som kan ge upphov till allvarliga sjukdomsfall under predisponerande förhållanden.
